1 kg of air in an insulated rigid tank of volume 1 m3is churned with a friction-less fan (see figure below) of 600 W capacity for 10 minutes. The fan efficiency is 100 %. Treating air as an ideal gas and neglecting kinetic and potential energy changes, what is the increase of pressure, to the nearest kPa? _________
